The selection of valuable features is crucial in pattern recognition. In this paper we deal with the issue that part of features originate from directional instead of common linear data. Both for directional and linear data a theory for a statistical modeling exists. However, none of these theories gives an integrated solution to problems, where linear and directional variables are to be combin...

In this paper, we describe initial efforts at Hewlett-Packard Labs, Bangalore, to create datasets of online handwriting in Indic scripts to support research in online handwriting recognition for the Indic scripts. The term “online” here refers to the fact that handwriting is captured as a stream of (x,y) points using an appropriate pen position sensor (often called a digitizer), rather than as ...

1 Part of this work was done under grant 001BA40 with France Telecom R&D Abstract A major feature of new mobiles terminals using penbased interfaces, such as personal assistants or e-book, is their personal character, implying that a good interface should be easily customizable in order to meet various users’ needs. We proposed recently a new recognition engine with strong adaptation abilities ...

The last two decades witnessed some advances in the development of an Arabic character recognition (CR) system. Arabic CR faces technical problems not encountered in any other language that make Arabic CR systems achieve relatively low accuracy and retards establishing them as market products. We propose the basic stages towards a system that attacks the problem of recognizing online Arabic cur...

Current interfaces for entering mathematical equations on computers are arguably limited and cumbersome. Mathematical notations have evolved to aid symbolic thinking and yet text-based interfaces relying on keyboard-and-mouse input do not take advantage of the natural two-dimensional aspects of mathematical equations. Due to its similarities to paper-based mathematics, pen-based handwriting inp...
